Problems solved by technology

Often the lack of a sufficient amount of pivots limited the positionable capabilities of the support arm and the flat panel display about a sufficient number of pivotal axes.
Lack of friction control and dynamic lift capability made adjustment of the flat panel display difficult and required the use of two hands to accomplish an adjustment.
However, movement in an upward direction was not so easily and readily accomplished, as the upward force required to raise the flat panel display had to overcome the friction of the friction style joint as well as the force of gravity.
In addition, two-handed adjustments added to the complexity of adjusting the flat panel display.

Embodiment Construction

FIGS. 7-10 are side views in partial cutaway of the vertical surface mount 10 showing various positionings of the support arm 24 along its 180.degree. pivot range 191 about horizontal axis 28 shown in FIG. 1. The three-axis pivot 30 and the flat panel display 16 are not illustrated for purposes of brevity and clarity. In these particular examples the gas spring mount 140 is adjusted to the maximum load position, thus providing the greatest offset from horizontal pivot axis 28, providing the greatest gas spring assistance. As adjustable gas spring mount 140 is adjusted closer to the horizontal axis 28, the counterbalance pivot point is lessened, which is desirable with smaller, lighter loads. Infinite adjustability within a range of payloads is desirable and attainable with this design. Also illustrated is the ability of the support arm 24 to travel from +90.degree. (vertical up position) to -90.degree. (vertical down position).

It should be noted that for each and every various monit...

Abstract

Multi-jointed and pivoted mounting systems for support of a flat panel video display and / or keyboard tray, incorporating a plurality of pivot points providing for pivotal motion of one or more components about a plurality of vertical and horizontal axes. Support arms having elevational pivot assemblies, including plastic friction washers and gas springs, offer elevational arm control requiring constant and predetermined positioning effort on the part of the video display operator and keyboard operator.

Description

1. Field of the InventionThe present invention is for mounting systems incorporating a positionable support arm, and more particularly pertains to mounting systems used for supporting a flat panel display in position for viewing or a keyboard in position for operating.2. Description of the Prior ArtPrior art mounting systems with positionable support arms have incorporated ball gimbals, simple knob operated pivot mounts, angular slots, and control arms or spring devices which were adjusted to maintain position of a flat panel display supported thereby while offering pivotable capabilities about a small number of pivot centers. Often the lack of a sufficient amount of pivots limited the positionable capabilities of the support arm and the flat panel display about a sufficient number of pivotal axes. Lack of friction control and dynamic lift capability made adjustment of the flat panel display difficult and required the use of two hands to accomplish an adjustment. Additionally, movem...
